So...De-extinction is the process of creating an organism which is – or greatly resembles – a member of an extinct species (1). Contemporary biotechnology offers various promising alternatives for achieving this purpose, including the techniques that have already been applied to preserving endangered species (2). De-extinction requires an in-depth study of the biophysical conditions where the species can live and reproduce in relation to other species – including humans – and adapt to the environmental changes. In any case, risk and harm evaluation on the impact of the “re-birth” of species is necessary. There is a number of crucial ethical issues concerning de-extinction. They include the meanings of concepts such as “nature,” “species,” “evolution,” “biodiversity,” “death,” and “wildlife” in relation to human behavior and human impact on nature (3). In 2013, de-extinction became popular through press and public events; the National Geographic devoted a cover story to this topic and presented various possibilities and scenarios about the most suitable candidates. The Revive & Restore network, with the support of TED and in partnership with the National Geographic Society, convened the TEDxDeExtinction conference bringing together conservationists, genetic technology practitioners, scientists, and ethicists (http://www.ted.com/tedx/events/7650). Because the revival of extinct animals inspires imagination (4), de-extinction has been a topic of science fiction novels, such as John Brosnan’s Carnosaur (1984) and Michael Crichton’s Jurassic Park (1990) and their film adaptations.

Following a systematic philosophical and ethical analysis on animal de-extinction in the context of ecological restoration (3), this article analyzes de-extinction from the standpoint of bio-objectification and considers how de-extinction is a case of bio-objectification.

It’s very important to choose the right food nowadays. Healthy and balanced diet is useful for every person. We depend on food as well as the cars depend on gas, for example. It’s our natural fuel, which gives our body physical strength and health. When the body is healthy, the mind will also be healthy. Different types of food contain different nutrients for our body. Some supply us with carbohydrates, some with proteins or fats, some with vitamins and minerals, etc. Many people think that fat is bad for people and they try to cut down on it. There is even a special line of products, called low-fat. The problem is that we do need some kinds of fat, but the saturated fats from animal products, like red meat, butter and cheese, can be really bad for health. Friendly fats can be found in avocados, nuts and seeds, olives and tuna fish, and in some other products. Some people cut down on too much sugar and salt, which is also a good idea. One of the healthiest types of food is fruit and vegetables. Such organic products can be only useful if they don’t contain any chemicals and additives, which has become a common phenomenon in modern supermarkets. More and more people tend to grow fruit and vegetables in their own gardens, instead of buying them. Another problem is modified food. It’s much cheaper than ordinary food, which is why people often buy it. From the other hand, modified food can lead to dangerous diseases. The food people eat depends a lot on their culture, religion, beliefs, health and other factors. However, some rules are common for everyone. They are: less fat, sugar and salt; and more water, vitamins, fresh fruit and vegetables.
